Jean-Christophe Bureau and Houssein Guimbard and Sébastien Jean (2017) Agricultural Trade Liberalization in the 21st Century: Has it Done the Business? CEPII Working Paper N°2017-11, June 2017

Based on a novel, detailed, time-consistent tariff database to take stock of developments regarding import protection in the agricultural sector since 2001, we propose a statistical decomposition of the changes in the various types of tariffs. The results show that the multilateral system has played a limited role in trade liberalization over the period. Many countries have continued to apply much lower tariffs on agricultural products than their WTO ceilings. Moreover, there has been substantial unilateral dismantling of tariffs over the period, so that much of the liberalization took place outside WTO and regional agreements. The number of regional trade agreements has surged, but their impact on applied agricultural tariffs has been limited. Finally, we investigate the tariffs, trade and production implications for food and agricultural products of two extreme scenarios in the future development of trade negotiations: an ambitious surge of regional agreements and a trade war within the WTO context.[Résumé des auteurs]
